This application claims the benefit and priority of US Provisional Application No. 61 / 234,369, filed August 17, 2009. The entire contents of this US provisional application are incorporated herein by reference.

(技術分野)
本開示は、外科手術用ステープル留めデバイスに関し、そしてより特定すると、アンビルがモータにより旋回させられ、そしてステープルが手動で発射される、道具アセンブリおよび内視鏡本体部分を有する内視鏡外科手術用ステープル留めデバイスに関する。
(Technical field)
The present disclosure relates to a surgical stapling device, and more particularly to an endoscopic surgical having a tool assembly and an endoscope body portion in which an anvil is pivoted by a motor and staples are manually fired. The present invention relates to a stapling device.

組織が最初に対向する顎構造体の間に把持またはクランプされ、次いで外科手術用ファスナーにより接合される、外科手術用デバイスは、当該分野において周知である。いくつかの器具において、これらのファスナーにより接合された組織を切断するためのナイフが提供される。これらのファスナーは代表的に、外科手術用ステープルの形態であるが、二部品ファスナーもまた利用され得る。   Surgical devices where tissue is first grasped or clamped between opposing jaw structures and then joined by a surgical fastener are well known in the art. In some instruments, a knife is provided to cut the tissue joined by these fasteners. These fasteners are typically in the form of surgical staples, but two-part fasteners can also be utilized.

この目的の器具は、2つの細長部材を備え得、これらの細長部材は、組織を捕捉またはクランプするためにそれぞれ使用される。代表的に、これらの部材のうちの1つは、ステープルカートリッジを有し、このステープルカートリッジは、少なくとも2つの横方向の列に配置された複数のステープルを収容する。他方の部材は、アンビルを有し、このアンビルは、ステープルがステープルカートリッジから駆動されるとステープルレッグを形成するための表面を規定する。一般に、ステープル留め操作は、ステープルカートリッジを通って長手軸方向に移動するカム棒またはカム楔によりなされ、これらのカム棒またはカム楔は、ステープルプッシャーに作用して、ステープルをステープルカートリッジから順番に排出する。ナイフがこれらのステープル列の間を移動して、ステープル留めされた組織をこれらのステープルの列の間で長手軸方向に切断し得、そして/または開き得る。このような器具は、例えば、特許文献1および特許文献2に開示されている。   The instrument for this purpose may comprise two elongate members, each used to capture or clamp tissue. Typically, one of these members has a staple cartridge that contains a plurality of staples arranged in at least two lateral rows. The other member has an anvil that defines a surface for forming a staple leg when the staple is driven from the staple cartridge. In general, the stapling operation is performed by cam bars or cam wedges that move longitudinally through the staple cartridge, which act on staple pushers to eject the staples sequentially from the staple cartridge. To do. A knife can be moved between the staple rows to cut and / or open the stapled tissue longitudinally between the staple rows. Such instruments are disclosed in, for example, Patent Document 1 and Patent Document 2.

特許文献3に開示される、後のステープラーは、2列のステープルを切開部の両側に適用する。このことは、カム部材が2セットの蛇行したステープル保有溝の間の細長案内経路を通って移動する、使い捨て装填ユニットを提供することにより達成される。ステープル駆動部材は、これらの溝内に位置し、そして長手軸方向に移動するカムにより接触されて、この使い捨て装填ユニットのステープルカートリッジからのステープルの排出を行うような様式で、配置される。このようなステープラーの他の例は、特許文献4および特許文献5に開示されている。   The latter stapler disclosed in U.S. Patent No. 6,099,056 applies two rows of staples to both sides of the incision. This is accomplished by providing a disposable loading unit in which the cam member moves through an elongated guide path between two sets of serpentine staple retaining grooves. The staple drive members are positioned in such a manner and are contacted by a longitudinally moving cam to dispose staples from the staple cartridge of the disposable loading unit. Other examples of such staplers are disclosed in US Pat.

上記器具の各々は、外科医が手術部位への直接的な手でのアクセスを有する、従来の外科手術手順において使用するために設計された。しかし、内視鏡手順または腹腔鏡手順において、外科手術は、小さい切開を通して実施されるか、または皮膚の小さい入口創傷を通して挿入される狭いカニューレを通して実施される。内視鏡および/または腹腔鏡での外科手術手順の特定の要求に取り組む目的で、内視鏡外科手術ステープル留めデバイスが開発されており、そして例えば、特許文献6(Greenら);特許文献7(Olsonら);特許文献8(Greenら);特許文献9(Greenら);特許文献10(Greenら);および特許文献11(Robinsonら)に開示されている。本願の譲受人であるU.S.Surgicalは、内視鏡用ステープル留め器具(例えば、Multifire ENDO GIA30器具およびMultifire ENDO GIA60器具)を、数年間製造および販売している。これらの器具は、有意な臨床的利点を提供した。それにもかかわらず、改善は可能である。 Each of the above instruments was designed for use in conventional surgical procedures where the surgeon has direct hand access to the surgical site. However, in endoscopic or laparoscopic procedures, surgery is performed through a small incision or through a narrow cannula inserted through a small entrance wound in the skin. In order to address the specific requirements of endoscopic and / or laparoscopic surgical procedures, endoscopic surgical stapling devices have been developed and are described, for example, in US Pat. (Olson et al.); Patent Literature 8 (Green et al.); Patent Literature 9 (Green et al.); Patent Literature 10 (Green et al.); And Patent Literature 11 (Robinson et al.). U.S., the assignee of the present application. S. Surgical has been producing and selling endoscopic stapling instruments (eg, Multifire ENDO GIA * 30 and Multifire ENDO GIA * 60 instruments) for several years. These devices provided significant clinical benefits. Nevertheless, improvements are possible.

内視鏡部分12は、この内視鏡部分と機械的に協働するように配置された、関節運動機構またはアクチュエータ24を有するように示されている。上で議論されたように、関節運動機構24は、エンドエフェクタ16を長手方向軸「A−A」に対して旋回させるように構成される。ここで、内視鏡部分12に作動可能に配置された関節運動ノブ26、および内視鏡部分12のハウジング30内に配置されたモータ28は、内視鏡部分12と係合したエンドエフェクタ16を関節運動させるために使用され得る。   Endoscopic portion 12 is shown having an articulation mechanism or actuator 24 disposed in mechanical cooperation with the endoscopic portion. As discussed above, the articulation mechanism 24 is configured to pivot the end effector 16 relative to the longitudinal axis “AA”. Here, an articulation knob 26 operatively disposed on the endoscope portion 12 and a motor 28 disposed within the housing 30 of the endoscope portion 12 include the end effector 16 engaged with the endoscope portion 12. Can be used to articulate.

モータ28は、関節運動を提供するために使用され、そして内視鏡部分12と作動可能に配置された少なくとも1つの電気端子32(1対の電気端子32aおよび32bが示されている)を有する。電気端子32は、内視鏡部分12のモータ28と電気的に連絡し、そしてハンドルアセンブリ10の伝導性リング18とモータ28との間で電力を連絡するように構成される。ここで、モータ28は、起動部材に作動可能に接続されて、この起動部材を実質的に長手方向軸A−Aに沿って移動させ、すなわち、エンドエフェクタ16を関節運動させる。モータ28は、エンドエフェクタ16の関節運動、内視鏡部分12の回転などのために有用な動力を供給するか、または動力の供給を補助することが想定される。   The motor 28 is used to provide articulation and has at least one electrical terminal 32 (a pair of electrical terminals 32a and 32b is shown) operatively disposed with the endoscope portion 12. . The electrical terminal 32 is configured to be in electrical communication with the motor 28 of the endoscope portion 12 and to communicate power between the conductive ring 18 of the handle assembly 10 and the motor 28. Here, the motor 28 is operably connected to the actuating member to move the actuating member substantially along the longitudinal axis AA, ie, articulate the end effector 16. It is envisioned that the motor 28 provides or assists in supplying power useful for articulation of the end effector 16, rotation of the endoscope portion 12, and the like.

伝導性リング18は、形状が実質的に円形であり、そしてハンドルアセンブリ10の遠位部分20の周りに配置される。理解され得るように、ハンドルアセンブリ10の遠位部分20の周りの、伝導性リング18の形状および/または構成は、内視鏡部分12がハンドルアセンブリ10に対して長手方向軸A−Aの周りで回転する際に、伝導性リング18と電気端子32との間の実質的に連続的な接触を可能にすることを補助する。従って、完全な360°の回転が可能である。さらに、モータ28と電気端子32との間の電力の連絡が、ハンドルアセンブリ10に対する内視鏡部分12の回転方向にかかわらず可能である。さらに、機械的止めおよび/または電気的止めが、内視鏡部分12および/またはハンドルアセンブリ10の遠位部分20に配置されて、内視鏡部分12の回転変位を制限し得ることが想定される。   The conductive ring 18 is substantially circular in shape and is disposed around the distal portion 20 of the handle assembly 10. As can be appreciated, the shape and / or configuration of the conductive ring 18 around the distal portion 20 of the handle assembly 10 is such that the endoscope portion 12 is about the longitudinal axis AA relative to the handle assembly 10. Helping to allow a substantially continuous contact between the conductive ring 18 and the electrical terminal 32 when rotating at. Therefore, a complete 360 ° rotation is possible. Further, power communication between the motor 28 and the electrical terminal 32 is possible regardless of the direction of rotation of the endoscope portion 12 relative to the handle assembly 10. Further, it is envisioned that a mechanical stop and / or an electrical stop may be disposed on the endoscope portion 12 and / or the distal portion 20 of the handle assembly 10 to limit the rotational displacement of the endoscope portion 12. The

1つの種類のみのエンドエフェクタ16が図1に図示されているが、数種類のエンドエフェクタ16(例えば、旋回可能なカートリッジアセンブリ、実質的に円形のカートリッジアセンブリを備えるエンドエフェクタ、平行な近接顎部材、ステープルの連続的な発射のために構成されたもの、および/またはステープルの同時の発射のために構成されたもの)が、外科手術用器具100に関連して使用され得、そして異なる種類の内視鏡部分12と一緒に使用可能であり得ることが、想定される。   Although only one type of end effector 16 is illustrated in FIG. 1, several types of end effector 16 (eg, an end effector with a pivotable cartridge assembly, a substantially circular cartridge assembly, parallel proximal jaw members, One configured for continuous firing of staples and / or one configured for simultaneous firing of staples) can be used in connection with surgical instrument 100, and within different types It is envisioned that it may be usable with endoscopic portion 12.

図3をさらに参照して、エンドエフェクタ16は、カートリッジアセンブリ40およびアンビルアセンブリ42を備える。カートリッジアセンブリ40およびアンビルアセンブリ42はさらに、1対の顎を規定する。カートリッジアセンブリ40は、複数のステープルおよび1つの駆動機構を収容する(図示せず)。駆動機構の1つの例は、2003年11月3日に出願された米国特許出願番号10/700,250に開示されており、その全内容は、本明細書中に参考として援用される。アンビルアセンブリ42は、カートリッジアセンブリ40に対して、カートリッジアセンブリ40から間隔を空けた開位置と、カートリッジアセンブリ40と並置して整列した近接位置またはクランプされた位置との間で移動可能である。あるいは、エンドエフェクタ16は、カートリッジアセンブリ40がアンビルアセンブリ42に対して移動可能であるように配置されてもよい。駆動機構(図示せず)は、駆動棒90による起動の際にカートリッジアセンブリ40から複数のステープルを排出するように構成される。駆動棒90は、起動シャフト80を介して可動ハンドル52に接続される。   With further reference to FIG. 3, the end effector 16 includes a cartridge assembly 40 and an anvil assembly 42. Cartridge assembly 40 and anvil assembly 42 further define a pair of jaws. The cartridge assembly 40 houses a plurality of staples and a drive mechanism (not shown). One example of a drive mechanism is disclosed in US patent application Ser. No. 10 / 700,250 filed Nov. 3, 2003, the entire contents of which are hereby incorporated by reference. The anvil assembly 42 is movable relative to the cartridge assembly 40 between an open position spaced from the cartridge assembly 40 and a proximal or clamped position juxtaposed and aligned with the cartridge assembly 40. Alternatively, end effector 16 may be arranged such that cartridge assembly 40 is movable relative to anvil assembly 42. A drive mechanism (not shown) is configured to eject a plurality of staples from the cartridge assembly 40 upon activation by the drive rod 90. The drive rod 90 is connected to the movable handle 52 via the activation shaft 80.

スイッチ60(図1)は、可動ハンドル52の機能を、把持または「発射」モードと「戻し」モードとの間で切り替えるように構成される。発射モードにおいて、エンドエフェクタ16は、把持用顎機構として働くように構成される。すなわち、アンビルアセンブリ42は、カートリッジアセンブリ40に対して、これらのアセンブリの間に組織を把持し、そしてこの組織を通してファスナーを適用するように移動可能である。戻しモードにおいて、エンドエフェクタ16は、解放機構として働くように構成される。すなわち、アンビルアセンブリ42は、カートリッジアセンブリ40に対して、組織を解放するように移動可能である。   The switch 60 (FIG. 1) is configured to switch the function of the movable handle 52 between a grip or “fire” mode and a “return” mode. In the firing mode, the end effector 16 is configured to act as a gripping jaw mechanism. That is, the anvil assembly 42 is movable relative to the cartridge assembly 40 to grasp tissue between the assemblies and apply a fastener through the tissue. In the return mode, the end effector 16 is configured to act as a release mechanism. That is, the anvil assembly 42 is movable relative to the cartridge assembly 40 to release tissue.

スイッチ60は、スライドカム62を備える。スイッチ60は、外科医の指により係合されて、スライドカム62をハンドルアセンブリ内の起動シャフト80に沿って移動させるように構成される。理解されるように、スイッチ60に対する代替物もまた想定される(例えば、ノブ、レバー、押しボタン、トグル、トリガアセンブリなど)。   The switch 60 includes a slide cam 62. Switch 60 is configured to be engaged by the surgeon's finger to move slide cam 62 along activation shaft 80 within the handle assembly. As will be appreciated, alternatives to the switch 60 are also envisioned (eg, knobs, levers, push buttons, toggles, trigger assemblies, etc.).

ハンドルアセンブリ10は、1対の成形された半セクション11aおよび11b(図2)から形成されたハウジング11を備え、このハウジングは、静止ハンドル50を形成する。半セクション11aおよび11bは、熱可塑性材料(例えば、ポリカーボネート)から形成される。あるいは、必要な強度要件を有する他の材料(例えば、外科手術等級の金属)が、ハウジング11を形成するために使用され得る。ハウジング11の半セクション11aおよび11bは、公知の固定技術(例えば、接着剤、溶接、相互に噛み合う構造体、ねじなど)を使用して、互いに固定される。あるいは、他の固定技術が使用されてもよい。   The handle assembly 10 includes a housing 11 formed from a pair of molded half sections 11a and 11b (FIG. 2), which forms a stationary handle 50. Half sections 11a and 11b are formed from a thermoplastic material (eg polycarbonate). Alternatively, other materials having the necessary strength requirements (eg, surgical grade metal) can be used to form the housing 11. The half sections 11a and 11b of the housing 11 are secured to each other using known securing techniques (eg, adhesives, welding, interlocking structures, screws, etc.). Alternatively, other fixation techniques may be used.

図1を参照すると、可動ハンドル52は、ハウジング半セクション11aと11bとの間に回転可能に支持される。付勢部材(図示せず)(例えば、ねじりばね)が、可動ハンドル52を静止ハンドル50から離して非圧縮位置まで推進するために備えられ得る。図3に示されるように、前進つめ70は、可動ハンドル52に回転可能に支持され、そしてばね(図示せず)によって、起動シャフト80の方へと付勢される。戻しつめ72もまた、可動ハンドル52に回転可能に支持され、そしてばね(図示せず)によって、起動シャフト80の方へと付勢される。   Referring to FIG. 1, the movable handle 52 is rotatably supported between the housing half sections 11a and 11b. A biasing member (not shown) (eg, a torsion spring) may be provided to propel the movable handle 52 away from the stationary handle 50 to the uncompressed position. As shown in FIG. 3, the advance pawl 70 is rotatably supported on the movable handle 52 and is biased toward the activation shaft 80 by a spring (not shown). A return pawl 72 is also rotatably supported on the movable handle 52 and is biased toward the activation shaft 80 by a spring (not shown).

起動シャフト80は、ハウジング11内で後退位置と前進位置との間でスライド可能に支持され、そして駆動棒90の近位端92を回転可能に受容するように構成された凹部82を規定する遠位端を備える。起動シャフト80は、第一の歯付きラック84および第二の歯付きラック86を備える。前進つめ70は、係合フィンガー70aを有し、係合フィンガー70aは、ばね(図示せず)によって、起動シャフト80の歯付きラック84の方へと付勢される。戻しつめ72は、係合フィンガー72aを有し、係合フィンガー72aは、ばね(図示せず)によって、起動シャフト80の第二の歯付きラック86の方へと付勢される。   The activation shaft 80 is slidably supported within the housing 11 between a retracted position and an advanced position and defines a recess 82 that is configured to rotatably receive the proximal end 92 of the drive rod 90. It has a rear end. The activation shaft 80 includes a first toothed rack 84 and a second toothed rack 86. The advance pawl 70 has an engagement finger 70a that is biased toward the toothed rack 84 of the activation shaft 80 by a spring (not shown). The return pawl 72 has an engagement finger 72a that is biased toward the second toothed rack 86 of the activation shaft 80 by a spring (not shown).

スライドカム62は、起動シャフト80の近くに配置され、そしてスイッチ60の移動によって、発射位置から戻し位置まで移動可能である。この発射位置において、スライドカム62は、戻しつめ72の係合フィンガー72aと第二の歯付きラック86との間を移動する。スライドカム62が発射位置にある間に可動ハンドル52が起動される(すなわち、ねじりばね(図示せず)の付勢に逆らって静止ハンドル50の方へと旋回する)場合、前進つめ70の係合フィンガー70aは、起動シャフト80の第一の歯付きラック84と係合して、起動シャフト80および駆動棒90を遠位に前進させる。駆動棒90が前進すると、アンビルアセンブリ42とカートリッジアセンブリ40との間の組織が圧縮されて駆動機構(図示せず)がカートリッジアセンブリ40からファスナーを排出するまで、アンビルアセンブリ42がカートリッジアセンブリ40の方へと移動する。   The slide cam 62 is disposed near the activation shaft 80 and can be moved from the firing position to the return position by the movement of the switch 60. In this firing position, the slide cam 62 moves between the engagement finger 72 a of the return pawl 72 and the second toothed rack 86. When the movable handle 52 is activated while the slide cam 62 is in the firing position (ie, pivots toward the stationary handle 50 against the bias of a torsion spring (not shown)), the engagement of the forward pawl 70 The mating finger 70a engages the first toothed rack 84 of the activation shaft 80 to advance the activation shaft 80 and drive rod 90 distally. As the drive rod 90 advances, the anvil assembly 42 moves toward the cartridge assembly 40 until the tissue between the anvil assembly 42 and the cartridge assembly 40 is compressed and a drive mechanism (not shown) ejects the fasteners from the cartridge assembly 40. Move to.

戻し位置において、スライドカム62は、前進つめ70の係合フィンガー70aと第一の歯付きラック84との間に移動する。スライドカム62が戻し位置にある間に可動ハンドル52が起動される(すなわち、ねじりばね(図示せず)の付勢に逆らって静止ハンドル50の方へと旋回する)場合、戻しつめ72の係合フィンガー72aは、起動シャフト80の第二の歯付きラック86と係合して、起動シャフト80および駆動棒90を近位に引き込む。駆動棒90が引き込まれるにつれて、アンビルアセンブリ42はカートリッジアセンブリ40から離れる方向に移動して、組織を解放する。   In the return position, the slide cam 62 moves between the engagement finger 70 a of the advance pawl 70 and the first toothed rack 84. If the movable handle 52 is activated while the slide cam 62 is in the return position (ie, pivots toward the stationary handle 50 against the bias of a torsion spring (not shown)), the engagement of the return pawl 72 The mating finger 72a engages the second toothed rack 86 of the activation shaft 80 to retract the activation shaft 80 and the drive rod 90 proximally. As drive rod 90 is retracted, anvil assembly 42 moves away from cartridge assembly 40 to release tissue.

ここで図4を参照すると、外科手術用器具200の別の実施形態は、レバー260に接続されたスライドカム262を備える。レバー260は、上記スイッチ60と同様に働いて、スライドカム262を発射位置から戻し位置まで移動させる。   Referring now to FIG. 4, another embodiment of the surgical instrument 200 includes a slide cam 262 connected to a lever 260. The lever 260 works similarly to the switch 60 and moves the slide cam 262 from the firing position to the return position.
